category and cannot be disabled at system start-up by
pressing <
CTRL >< ENTER >.
To unlock the system password, you must enter the setup
password and then change the
PASSWORD STATUS cate-
gory to UNLOCKED . In this state, the system password
can be disabled at system start-up by pressing
<
CTRL >< ENTER > and then changed through the SYSTEM
PASSWORD category.
Boot Sequence
BOOT SEQUENCE can be set to DISKETTE FIRST (the
default option) or HARD DISK ONLY .
The term boot refers to the sy stem’s start-up pro-
cedure. When turned on, the sy stem “bootstraps”
itself into an operational state by loading into memory
a small program, which in turn loads the necessary
operating sy stem.
BOOT SEQUENCE tells the sy stem
where to look for the files that it needs to load.
Selecting DISKETTE FIRST causes the sy stem to try
booting from drive A first. If it finds a diskette that is
not bootable in the drive or finds a problem with the
drive itself, the sy stem display s an error message. If it
does not find a diskette in the drive, the sy stem then
tries to boot from the hard-disk drive (drive 0).
Selecting HARD DISK ONLY causes the sy stem to boot
only from the hard-disk drive, even if there is a boot-
able diskette in drive A.
Setup Password
SETUP PASSWORD lets you restrict access to your com-
puter’s System Setup program in the same way that you
restrict access to your system with the system password
feature. The options are:
• NOT ENABLED (the default option)
•
ENABLED
•
DISABLED BY JUMPER
NOTE: Read “Using the Setup Password Feature” found
later in this chapter for instructions on assigning a setup
password and using or changing an existing setup pass-
word. See “Disabling a Forgotten Password” found later
in this chapter for instructions on disabling a forgotten
setup password.
Auto Power On
AUTO POWER ON allows you to set the time and days of
the week to turn on the computer system automatically.
You can set
AUTO POWER ON to turn on the system either
every day or every Monday through Friday.
NOTE: This feature will not work if you shut off your sys-
tem using a power strip or surge protector.
Time is kept in a 24-hour format (hours:minutes). To
change the start-up time, press the right-arrow key to
increase the number in the highlighted field or press the
left-arrow key to decrease the number. If you prefer, you
can type numbers in both of the appropriate fields.
The default for AUTO POWER ON is DISABLED .
Power Management
For certain types of monitors and most EIDE hard-disk
drives, you can reduce system power consumption by
enabling the power management feature. With
POWER
MANAGEMENT enabled, these monitors and drives automati-
cally switch into low-power mode during periods of system
inactivity.
POWER MANAGEMENT can be implemented at three
levels— MAXIMUM , REGULAR , and MINIMUM. (The differ-
ent levels apply to the monitor only; hard-disk drive
operation is the same for all three.) The default setting for
this category is
DISABLED .
Saving Monitor Power
If you have a Video Electronics Standards Association
(VESA
®
) Display Power Management Signaling (DPMS)-
compliant monitor, enabling the POWER MANAGEMENT
category reduces monitor power consumption during periods
of keyboard and mouse inactivity.
NOTE: The power management feature monitors activity of
a mouse connected to the Personal System/2 (PS/2)-
compatible mouse port.
CAUTION: Check your monitor documentation to
make sure you have a DPMS-compliant monitor
before you enable this feature. Otherwise, you risk
damaging the monitor.
